669402 ÷ 72 
Let's see how many times 72 fits into 669402.

On to step 1:
If we divide 6 by 72, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 72

Step 2:
If we divide 66 by 72, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 72

Advancing to step 3:
669 divided by 72 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 648 from 669 and we're left with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 72

Moving on to step 4:
If we divide 214 by 72, we get 2 and a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
The remainder is 70 after subtracting 144 from 214.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 72

Step 5:
72 can be fit into 700 9 times, resulting in a remainder of 52.
The next digit of our result is 9. 
Result so far: 929.0
Subtract 648 from 700 to get 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 72

Going ahead to step 6:
When dividing 522 by 72, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 9297.0
If we subtract 504 from 522, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
The number 72 fits into 180 2 times, leaving a remainder of 36.
The next digit of our result is 2. 
Result so far: 9297.2
The remainder is 36 after subtracting 144 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 72 fits into 360 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 9297.25
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 72 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9297.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 72 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9297.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9297.25, and the remainder is 0.0.
